1. 以下关系型数据库中的表和数据,要求将其转换为适合于HBase存储的表并插入数据:
学生表(Student)(不包括最后一列)
学号(S_No)
姓名(S_Name)
性别(S_Sex)
年龄(S_Age)
课程(course)
2015001
Zhangsan
male
23
2015003
Mary
female
22
2015003
Lisi
male
24
数学(Math)85
create 'Student', ' S_No ','S_Name', ’S_Sex’,'S_Age' put 'Student','s001','S_No','2015001' put 'Student','s001','S_Name','Zhangsan' put 'Student','s001','S_Sex','male' put 'Student','s001','S_Age','23' put 'Student','s002','S_No','2015003' put 'Student','s002','S_Name','Mary' put 'Student','s002','S_Sex','female' put 'Student','s002','S_Age','22' put 'Student','s003','S_No','2015003' put 'Student','s003','S_Name','Lisi' put 'Student','s003','S_Sex','male' put 'Student','s003','S_Age','24'
2. 用Hadoop提供的HBase Shell命令完成相同任务:
列出HBase所有的表的相关信息;list在终端打印出学生表的所有记录数据;向学生表添加课程列族;向课程列族添加数学列并登记成绩为85;删除课程列;统计表的行数;count 's1'清空指定的表的所有记录数据;truncate 's1' list scan 'Student' alter ‘Student',NAME=>'course' put 'Student','3','course:Math','85' dorp 'Student','course' count 'Student' truncate 'Student'
